Maxillary canine impaction is an anomaly often encountered in children. Although it has been reported that the incidence of palatally impacted canines is higher than that of labially impacted ones, it has been found that labial impaction of canines is more common than palatal impaction in Asian populations. In the cases presented here, maxillary canines were guided normally after rapid palatal expansion, followed by modification of root angulation of neighboring lateral incisors in 8-10-year-old children who had maxillary canines suspected of labial impaction. Consequently, the method of modifying the root angulation of the maxillary lateral incisor, combined with rapid palatal expansion, is effective in preventing impaction of an ectopically erupting maxillary canine without resorting to surgical methods.
